That is, instead of doing very long calculation in a single clock cycle, and by that requiring the clock cycle being very long (low frequency), we break the calculation to many small ones, and by that doing more clock cycles, but the clock …

WebJan 6, 2014 · The scheme you describe is what I would call a 'req/ack 4-phase handshake', in that it takes four clock cycles to send one data. 1. req=1 ack=0 2. req=1 ack=1 3. req=0 ack=1 4. req=0 ack=0. This kind of interface would be better when doing an asynchronous request across a clock boundary, as it eliminates any possibility of interpreting a packet ...
